Unit 1: Noise Pollution [SCMEU01]

Noise pollution is unwanted sound, dumped into the atmosphere without regard to the adverse effects it

may have. One can define noise pollution as those sounds which are undesired causing discomfort in

hearing. The pollution can be measured by the sound intensity. The unit of sound intensity is decibel

[dB]. Very high sound intensity beyond the threshold of hearing can be the threshold of pain which may

cause damage to ear leading to hearing impairment. The following table shows permissible noise levels in

the case of industrial, commercial and residential areas and silence zone.

Sources of Noise Pollution: There are two main sources of noise pollution:

(a) Industrial Sources: These may include noise from various factories, workshops and warehouses with

heavy machinery, producing sound with higher intensity.

(b) Non-industrial Sources: These include the following sources of noise pollution:

Loudspeakers and Fire Crackers during festivities and ceremonies.

Domestic Appliances used in large scale.

Means of Transport in urban and rural areas for personal, public and agricultural uses.

Question 1 [Q01]

The city counsellor proposes the construction of a hospital near a huge industrial plot where operations

continue round the clock. Is this decision appropriate? Justify your answer.

In India, Diwali is a traditional festival of lights. But since a long time use of firecrackers has been an

integral part of this festival. Research studies have shown that along with severe air-pollution, the

rampant use of fire-crackers cause severe sound pollution as well. Following data shows the extent of

such sound pollution. The figure shows the level of sound intensity in different locations of four major

cities during the day and night on Diwali.

Question 3 [Q03]

Identify from the graph the place(s) where people used firecrackers with the same intensity throughout

the day as well as night.

Question 4 [Q04]

The unit of measuring sound is

A. Joules

B. Decibel

C. Pascal

D. Lux

Question 5 [Q05]

Based on the data given in the graph, select the statement which is incorrect.

A. In none of the reported areas in Hyderabad, has the intensity of sound due to the use of firecrackers at

Diwali night has been higher the night of Diwali than the day of using fire crackers.

B. The approximate difference of using fire crackers on the day and night of Diwali has been same in

Thane and JNTU.

C. In none of the reported areas did the sound intensity increase above the day time limit for industrial

zones.

D. Chinhat is an area where the sound intensity for residential area for night was not breached.

Unit 2: Heat Transfer [SCMEU02]

Heat is always moving! If you have two objects or substances that are at different temperatures, heat will

always move OUT of the warmer object or substance, and INTO the cooler object or substance. This heat

transfer will continue until both the objects are the same temperature. This is called heat transfer. Heat

can transfer (or move) in 3 ways: conduction, convection, and radiation.

Conduction is how heat transfers through direct contact with objects that are touching. Any time that two

objects or substances touch, the hotter object passes heat to the cooler object.

Convection is how heat passes through fluids. A fluid is anything that has loosely moving molecules that

can move easily from one place to another. Liquids and gases are fluids. In fluids the molecules spread

out and move apart when they get hot. The hot fluid becomes less dense and rises up. Cooler fluids are

more dense and so it sinks down. This up-and-down motion creates what are called convection currents.

Radiation is how heat moves through places where there are no molecules or particles. Radiation is

actually a form of electromagnetic energy. Radiation is heat moving in waves. Radiation does not need

molecules or any particles to pass the energy along.

Question 6[Q01]

Write down the process of heat transfer in the following cases.

(i) The heat you feel on your chair when you stand up was transferred from your skin.

(ii) A room warms up in time when more and more people fill it up.

Question 7 [Q02]

Identify the processes (1, 2, and 3) of heat transfer in the above figure and pick the correct option which

indicates them.

A Conduction Convection Radiation

B Convection Conduction Radiation

C Radiation Convection Conduction

D Convection Radiation Conduction

Question 8: [Q03]

What method of heat transfer can occurs in a vaccum? Give reason to support your answer.

A. Conduction only

B. Convection only

C. Radiation only

D. Conduction and Convention

Unit 3: Natural Adaptation [SCMEU03]

Body Form and Size as Adaptations to Temperature Stress

The eco-geographical rule formulated by Joel Asaph Allen in 1877 states that animals that are adapted to

colder climates tend to have shorter limbs and body appendages in comparison to animals that are

adapted to more warm climates. It predicts that the body surface area-to-volume ratio of animals and

birds tends to vary with the average temperature in which they occur. This results in lower ratios in colder

climates and higher ratios in hotter climates.

Allen’s Rule: Body form or shape is linear in warm climates and more rounded and compact in cold

climates. Round forms have a smaller surface area to volume ratios.

Bergmann’s Rule: Body size is large in cold climates and small in warm climates. Large bodies have a

smaller surface area to volume ratios.

Both of these rules cause systematic changes in the surface area to volume ratios.

• In cold climates where you need to retain heat, bodies are larger and more compact.

• In warm climates where you need to expel heat, bodies are smaller and more linear.

Following figure shows the correlation between ear length and air temperature for hares (genus Lepus)

and foxes.

Based on the paragraph given and the data in the above table, answer the following questions.

Question 9[Q01]

(i) Using Allen’s rule to pick the statement is correct and give justifications for them.

A. From right to left the climate tends to be increasingly colder.

B. From right to left the climate tends to be increasingly warmer.

What will be the appropriate living environment for the O3 and O4?

(i) O3-small animals: .........................................................

(ii) O4-larger animals: .........................................................

Features Small Animals Large Animals

Surface Area Large Small

Volume Small Large

Surface Area to Volume Ratio High Low

Living Environment O3 =? O4 =?

Question 11 [Q03]

Using your knowledge of surface area to volume ratios, suggest why the hippo spends most of the day

partly submerged in lakes and rivers, coming out at night to feed on vegetation.
